4 Int. or. host 11/44 US. Cl. 49351 3 Claims ABSTRACT OF THE DISCLOSURE The present invention relates to thin doors, for example, thin sliding windows which have to pass between two door walls, which are very close to one another, or which doors project only silghtly beyond the width of a vehicle.

Conventional window raising devices are relatively thick, particularly in the region of the axis of the control crank; it is, as a result, impossible to introduce a window-raising device of this kind into the panels of a thin door prior to assembly of such door.

The object of the present invention is to provide a door having a window-raising device, in which the assembly of the window-raising device is made possible without it being necessary to modify the structure and to render the panels thereof more rigid.

According to the present invention there is provided in a door having a slidable window glass, a window glassopening adjustment device including an assembly mounting the window glass, a gear-toothed sector pivotally secured to a part of the assembly, a crank rotatably mounted on the door, and a pinion fast for rotation with the crank and meshing with the sector, winding movement of the crank causing rotation of the sector and hence movement of the window.

An embodiment of a window-winding mechanism, in accordance with the invention will now be described, by way of example, with reference to the sole figure of the accompanying drawings which is an internal view of a part of the door, parts being broken away.

Referring to the drawing, there is seen a portion of a door which is, for example slideably mounted with respect to a framework, not shown, and which comprises two sheet metal members 1 and 2 assembled together with a predetermined space between them.

A plate 3 is fixed to the sheet metal member 1 between this piece of sheet metal member and the sheet metal member 2 by screws 4 at one of its ends and by screws 5 at its other end.

There are pivotally mounted in the plate 3, respectively at 6 and 7, a link 8a and a toothed sector 9 carried by a link 8b extending parallel to the link 8a. The links 8a and 8b are pivotally mounted on a small plate 10. The

3,495,357 Patented Feb. 17, 1970 latter is connected by parallel pivotal links 11 to clamps 12 and secured on the glass 13.

The assembly formed by the plate 3 and 10, the toothed sector 9 and the links 8a, 8b and 11 is of relatively small thickness and thus easily located between the sheet metal members 1 and 2.

When the toothed sector 9 turns clockwise, from the position shown, the small plate 10 moves in an arc of a circle and the glass 13 descends. The movement of this glass can be substantially rectilinear, if, as it is usual, means are provided for guiding the glass parallel to one of the lateral edges of its framework.

A small plate 14 is fixed on the sheet metal member 1 by screws 5. On this plate there is mounted a casing 15 in which the control crank 16 can pivot and which contains a conventional self-locking device for the crank. The spindle of the crank 16 passes through the plate 3 and carries a pinion in engagement with the toothed sector 9.

I claim:

1. In a door having a slidable window, said door comprising a pair of panels with a space therebetween, a window opening device within said space comprising an assembly mounting said window, a gear-toothed sector within said space pivotally secured to a part of the assembly, a plate mounted on the outer surface of one Of said panels, a crank and a bearing support therefor mounted on said plate externally of the door, said crank having a shaft with one end thereof passing through said one panel into said space, a pinion in said space fixed to said one end portion of said shaft and meshing with said gear-toothed sector, whereby winding movement of the crank causes rotation of said sector and hence sliding movement of said window, said mounting assembly, gear sector, and pinion being constructed and arranged to occupy a minimum width, so that the spacing between the pair of door panels may be relatively small to facilitate provision of a thin door which is adapted to slide in a narrow space between two Walls of a motor vehicle or the like.

2. A door according to claim 1, wherein said mounting assembly includes a pair of clamps secured to the window glass,

a pair of links each pivotally secured to a respective said clamp, and

a second plate interconnecting the links and spaced from said clamps,

said sector being pivotally secured to the said plate.

3. A door according to claim 2, wherein said mounting assembly further comprises a third plate secured to the door, and

an elongate link pivotally connected both to said third plate and said second plate.
